Ultrasonic Cold Cooling Meters Meter Residential Ultrasonic Cooling Meter ULTRACOLD T350 (2WR6...) A customer tailored cooling meter designed for residential needs and easy billing
T350 Highest measurement accuracy ULTRACOLD T350 measures flow rate by the ultrasonic dragging principle. Two transducers alternatively transmit ultrasonic signals in and against the direction of flow. The flow rate can be precisely calculated from the difference between the measured propagation times. Future-oriented Ultrasonic technology is an innovative, sensible and futureoriented basis for cold measurement in both economic and ecological terms. The measuring tube of the ULTRACOLD T350 has a robust allmetal design and is fitted with the special internal profile Dura- Surface. Interfering reflections in the measurement channel are filtered out from the outset. That makes the meter more resistant to dirt deposits. The advantages are obvious: technical superiority and no wearing parts. It is the excellent reliability that counts. Long-life service and simple low-cost inspection and recalibration Ultrasonic measurement requires no mechanical moving part or straight pipe sections and can be installed any way around. The measuring tube itself has a robust all-metal design. The cooling meter is insensitive to small particles in the water and operates silently. Reliable operation ULTRACOLD T350 features enormous measurement dynamics. For this reason, the volume measuring units can be loaded up to twice the nominal load qp. The response limit remains at a constant low level during the entire calibration period.
Enter a whole new world Our ULTRACOLD T350 (2WR6...) cooling meters are not only precise, allowing easy billing, but also reliable, long-lasting and low in cost for demand in building services technology. T350 cooling meters offer you numerous benefits without mechanical moving parts, which are not required for ultrasonic measurement.

T350 Stored meter readings You will receive stored meter readings on a set day of your choice or at the end of the month. The readings for the last 15 months for cooling, volume and missing times are shown on a practical, configured display. Generously sized display The displays are clearly structured and easy-to-understand, divided into an easily accessible customer area and a service area. Instantaneous values, set day values and monthly values can be shown. Display of all consumption values facilitates traceability and billing. Tailored selection the temperature sensor ULTRACOLD T350 works with permanently connected Pt 500 temperature sensors. We can supply not only the standard sensor Direct Short M10 x 27.5 mm for direct installation but also 5.2 x 45 mm sensors for pockets with cable length of 1.5 m or 5m. Installation accessories are available for the flow sensor whereas the return sensor is already mounted in the volume measuring unit. Future-proof communication With the M-Bus communication you are connected to the world and can collect data from anywhere via modem M-Bus/RS232 or TCP/IP.
